the Application in front of you in the first place, simple, but unusual and pretty features. Most non-standard of them — the search for unknown numbers out of your phone book (this requires Wi-Fi or mobile network, and the number is taken from a huge database Truecaller), but otherwise it's pretty normal but nice: sleek design in accordance with “material" concept, two themes to choose from, search through your saved contacts, call and creating messages through gestures (familiar to all users TouchWiz).
